Container glass is a type of glass for the production of glass containers, such as bottles, jars, drinkware, and bowls. Container glass stands in contrast to flat glass (used for windows , glass doors, transparent walls, windshields ) and glass fiber (used for thermal insulation , in fiberglass composites, and optical communication ).
Frit. A frit is a ceramic composition that has been fused, quenched, and granulated.Frits form an important part of the batches used in compounding enamels and ceramic glazes; the purpose of this pre-fusion is to render any soluble and/or toxic components insoluble by causing them to combine with silica and other added oxides.

Batch processing is one of the initial steps of the glass-making process. The batch house simply houses the raw materials in large silos (fed by truck or railcar), and holds anywhere from 1–5 days of material. Some batch systems include material processing such as raw material screening/sieve, drying, or pre-heating (i.e. cullet). Whether ...
The refractive, reflective and transmission properties of glass make glass suitable for manufacturing optical lenses, prisms, and optoelectronics materials. Extruded glass fibres have applications as optical fibres in communications networks, thermal insulating material when matted as glass wool to trap air, or in glass-fibre reinforced plastic ...
For example, an oxide of cobalt is used to make glass blue. [3] Broken and scrap glass, known as cullet, is often used as an ingredient to make new glass. The cullet melts faster than the other ingredients, which results in some savings in fuel cost for the furnace. Cullet can account for 25 to 50 percent of the batch. [4] The batch is placed ...
In the 1930s, Saint-Gobain of France first developed foam glass with calcium carbonate as a foaming agent. In 1932, it applied for a patent. [5]An early report of foam glass as a construction material was made by the Soviet scientist, Professor Isaak Ilych Kitaygorodskiy at the All-Union Conference on Standardization and Manufacture of New Construction Materials in Moscow in 1932.

Additional ingredients may be added to color the glass. For example, an oxide of cobalt is used to make glass blue. [3] Broken and scrap glass, known as cullet, is often used as an ingredient to make new glass. The cullet melts faster than the other ingredients, which results in some savings in fuel cost for the furnace. Cullet typically ...
Cer-vit is a family of glass-ceramic materials that were invented by Owens Illinois in the mid-1960s. Its principle ingredients are the oxides of lithium , aluminum and silicon . It is melted to form a glass which is then heat treated to nucleate and crystallize it into a material that is more than 90% microscopic crystals.
